I guess everyone who starts down that path may be tempted to close the doors to open source.

It's interesting you say that, I am trying to get to grips with the advantages/disadvantages of Rocket Stoves versus Gasifiers.

Rocket Stoves...seem to be very open source with a myriad of designs. From what I see, they provide two valuable functions. Space heating or/and Cooking.

The more I learn about Gasifiers the more I find they seem to be more versatile than Rocket Stoves. Gasifiers seem to accommodate fan assist with the heat advantage that brings and can store gas to drive your car, lawnmower, or gas stove.

I would be interested to learn which way you think the industry going....and why?

Here is a you-tube clip of French man using a simple propane bottle, some old discarded motor oil (I believe, my French is not that good) and adding some water.

My opinion, which is probably going to piss off everyone, is that the new rockets are gasifiers. That is the trend I have watched develop over the last year or so with the metal and RMH stoves. In fact, the RMHs from 2 years ago seem...well...ancient compared to what is coming out each day.

I would suggest any stove that uses secondary air to re burn the smoke from the initial burn is in fact a gasifing stove... doesn't matter if it's a simple or a complex build...

What if you have an RS type design stove, without secondary air?

I am not 100% convinced secondary air is a must have feature in a RS. Whats the purpose, if you have an efficient clean burn of all the fuel Vapor's the first time ?

I do understand why some RS stove designs may need secondary air. I personally, would rather figure out how to have a successfully burn the first time around, Saving time and money on the design and build.

I would say it is still a gasifing stove (rocket stoves in general)... as the heat from coals is gassing the wood above... a match burning is an example of gasifing even... the fact that a rocket stove is full open air means there is an over abundance of oxygen to begin with. we don't usually choke off a rocket stove....
